I found this story on @HistoryWeird's blog here. The original source was The Australian Advertiser (Albany, WA), February 3rd, 1896.
"In January 1896 a Miss Suider appeared before the Magistrates Court in Albany, Western Australia, charged with using indecent language in public. According to a press report the defendant said almost nothing during the hearing. On the instruction of her stepfather, she later offered an apology."
The punchline? She was seven years old and had "made herself drunk" on wine when her parents weren't around, and then apparently went around town cursing at people.
The article reads:
“The language used by the child and heard by several others was said to be filthy in the extreme… His Honour had a wish to convey the child to the reformatory but instead discharged her into the custody of her step-father, who advised the court that he was headed into the bush [Australian outback]. The magistrate warned the step-father and mother that it would be they held to account with a large fine, if the child was brought before him again.”
I would give anything to hear some examples of what she said during her bender.
